Porltand, OR. MOMS!!!!

Im a stay at home mother of two and daycare for one other. I'v lost most of my weight in camas, wa and now Ilive in Portland OR. Its alot diferent here when you look at all the options for transit and walking. I can take the max right to the zoo. But I really am tired of going alone. I dont want to sound deprite but im so excited to be more than halfway to my goal and I want to stay motivated. Does anyone now of any good mommy workout groups for walking or anyting???
